The Racetronix FIT-CP8QDF38CL connects -8 smooth-bore PTFE hose straight to a 3/8" male EFI quick-connect tube, such as the fuel rail, filter or pump outlet on many late-model vehicles. It fits Racetronix TFT-1165, TFT-1167, TFT-1168 and TFT-1170 PTFE hose, and comes with its FIT-CP8C aluminum crimp collar, crimped on with a hydraulic hose crimper.

Key features

• Hose side: crimp nipple for -8 smooth-bore PTFE hose (0.405" ID).
• Port end: 3/8" SAE J2044 quick-connect female, for a 3/8" male EFI tube.
• Straight.
• Crimp collar included: FIT-CP8C, 18.73 mm before crimping.
• Finished crimp OD: 16.7 mm on TFT-1167 and TFT-1170 hose, 17 mm on TFT-1165 and TFT-1168 hose.

Push the quick-connect fully onto the male tube until it clicks, then pull back on it to check that it is locked.

Making a crimp assembly

1. Tape, then mark. Wrap masking tape tightly around the hose where you will cut, so the braid does not fray, then measure and mark the cut on the tape, allowing for the length each fitting adds.
2. Cut square through the mark with a thin cut-off wheel (the thin Bosch wheels work well), not a thick grinding wheel. Remove the tape and trim any stray braid wires flush.
3. Trim back any coating. On black covered (B) hose, cut the Hytrel or PVC coating back from the crimp area so the collar sits directly on the braid.
4. Clean the hose. Blast the cut end and the bore with brake cleaner, then blow it out with compressed air to clear all cutting debris.
5. Slide the collar onto the hose.
6. Push the nipple fully into the hose until the hose bottoms against the fitting, then bring the collar up against the fitting so it covers the nipple.
7. Line up angled ends first. Once crimped, the fitting cannot be turned on the hose, so line the angle up with the other end of the assembly and mark the hose and fitting before you crimp.
8. Crimp with a die that covers the collar size, following your crimper’s instructions, to the finished outside diameter in the crimp chart for your hose.
9. Measure the crimp with calipers in at least three places around the collar and compare it with the chart. If it is under size (over-crimped), cut it off and make a new end.
10. Flush and cap. Blow the finished assembly through with solvent and compressed air, cap both ends until it is installed, and pressure-test it before use.
